Ok, I just have one plant, and I am sort of trying to learn on it more than anything right now. I grew this from a seed I found in a bag of purple kush. I am growing in soil (schultz premium potting soil plus 0.08-012-0.08), about 2 inches from the light (2 35w 2500 lumen flouro) in my closet. They are 5-6 months old. I have watered them about every second day, with 7.0 ph water. It's room temp about 72 F and low humidty. The pot is a foot wide and a foot deep. I had some thrips causing me some problems, at first I couldn't figure out what they were, and once I did they had done a bit of damage on the lower/older leaves, aka shiny spots etc. I went to the store and bought some bio friendly pesticide (Green Earth Bio Mist Insect Killer) that was for indoor use and claimed to rid plants of thrips. I mixed it 10:1 with water and sprayed it on my plants, two days later I have this happening..... http://postimage.org/image/2b90osgxw/ Other info: My PH I have only measured with a analog PH meter and it's about 7.5-8. I realize this is above ideal, and intend to fix it, does this damage look anything like a PH imbalance or something else, thanks.
Hi. I had a look and Im torn between damage from the spray vs Ph. I also wanna tell u to get rid of the soil and the nutes, but I wont. Reason being - it seems to be working out, save for the minor damage. Eventually tho, that Ph is gonna sneak up on the plant, and present itself rather harshly. Do u intend on flowering it or is it gonna be a mom ??? Cuz at 5 or 6 months old, she is just rarin to go. My advice to u is to get it used to a lower ph. I would start watering with 6.0 ph water, until it falls within the range of 6.3 - 6.8. Freak
Well I have been looking around, and my PH estimate might be way off because I used a analog soil tester, and I have read they aren't accurate. I plan on buying a digital ph tester soon. I have had no problems aside from the thrips, until I used that spray so I would say my PH is probably less likely than the spray damage. You said get rid of the nutes? I never listed any did I, but I have been using Miracle Grow 24-8-16, no good? Do you think that will be ok, or is it gonna effect my plant a lot? Also I am unsure about starting to flower it because it's still pretty weak looking and it's and indica so it won't grow much after veg from what I heard. Here is a picture of the full plant, it's not ready to flower is it? View image: photo (3)
No where near flower time lol. Are u sure its 5 - 6 months old ??? Is this the stuff u used ??? If it is, its a good product. Totally organic Pyrethrin. Very safe. The 10:1 ratio u used - is that concentrate to water, or vice versa ??? Freak
Ya, it is about 4-5 months old, since just after x-mas, but I had them under barely any light, it was just a 40w standard bulb in a desk light so their growth has been stunted. About 4 days ago I got the shop light with two 48 inch 32w T8 flouros. That is the exact product I used, and I mixed it water to concentrate. 500ml to 50ml concentrate. So you're saying it's safe? Could it still have caused that damage or am I looking at a ph or nute issue? I am looking for overall advice on this plant, I realize I had no clue what I was doing, and still don't but I want to finish this off, is it worth it trying to adjust PH and balance nutes on this and then letting it veg longer and then flower it, or am I wasting my time?
Its up to u wether or not u wanna make a go of it. IMO it would be a shame to get her this far and then just let her go to pot lol . Notice Im saying She. Maybe it is. Me, Id get her in shape and then let er rip. Its a Ph and nute problem. U need more light too. At least 100w of 6500k, to be exact. If u wanna make a go of it... Freak
Ok thanks. Any suggestions on how to bring down my ph, since there is many I have read. And yes I am planning on getting some CFT's going soon for more output. So does the lumen output matter, or as long as I have 100w of 6500k I should be ok?
There are many products out there that will bring down Ph. Most noteably Ph UP, and Ph DOWN. They work well. If u are strapped and in a tight spot, u can use lemon/lime juice or white vinegar as a stand in. But u shouldnt make a habit of it. Oh yes, its all about lumens/sq ft. 100w minimum 6500k CFLs. But load them on if ya want as the more light = better potency budz and a better root mass. Freak
